A method of detection weak moving target based on linear canonical ambiguity function

As a new time-frequency transformation, linear canonical ambiguity function (AFL) which combined the inherent peculiarities of the linear canonical transform (LCT) with the ambiguity function (AF) can estimate the signal with cubic phase effectively. In this paper, a new method based on the time delay cancellation of the AFL to detect the weak moving target with cubic phase in sea clutter is proposed. The theoretical analysis and simulations show the correctness and effectiveness of the proposed method.
